Numerical research on conjugate heat transfer from the combustion in furnace to the supercritical fluid in tube

This research numerically investigated the conjugate heat transfer between the combustion occurring inside a furnace and a supercritical fluid flowing through a tube. A mathematical model was developed and validated to simulate this coupled process. Utilizing this model, the study analyzed how abnormal heat transfer behaviors of the supercritical fluid within the tube, such as heat transfer enhancement or deterioration, influence the overall conjugate heat transfer mechanism. Additionally, the effects of variations in the combustion conditions inside the furnace were examined. The findings revealed that the heat transfer enhancement or deterioration phenomena associated with the supercritical fluid flow in the tube had minimal impact on the combustion process occurring within the furnace.
